Colombian chica pays back cheating boyfriend by writing all over his Mercedes

With a Sharpie and a lot of fury, a scorned Colombian woman recorded her revenge on her cheating boyfriend by writing all over his white Mercedes-Benz.

When Alejandra Samaniego, 25, found her 27-year-old boyfriend Pabil Muniz Quintanilla in bed with another woman she did not immediately flip her switch.

Instead, the woman from Barranquilla in the north of the South American country plotted to take her revenge out on something he probably cared for more than her.

Ms Samaniego waited a few hours and charmed her way into her unfaithful boyfriend's parking garage and went to town on his white Merc with a permanent marker while a friend recorded her payback as she went.

"Small penis", "Junkie slime" and "Crap sex" were just some of the epithets the broken-hearted now ex-girlfriend scrawled in Spanish all over the sports car.

The video of her giggling graffiti revenge that was posted to YouTube on Tuesday soon clocked-up more than 110,000 views with many comments from men and women giving her a massively encouraging "Vas chica!" — "You go girl."
